So, i Figured somethings wrong with CM9.0 alpha7 for the i9001 and that's something i've searched loooooooooooong enough to understand actually NO ONE has had this problem.First i had alpha 4 and with some searching in these forums i figured alpha 4 had wifi problems entirely.Then i downloaded alpha7........ thought my problems would go away but............. when doa clean install without the SIM inside my wifi works pretty good,but the moment i turn my phone off,insert SIM,and enter the PIN, my wifi...like,disappears on it's own.NOTHING WORKS!!!! i'm desperate to keep CM9.i even tried to wipe cache and dalvik cache and fix the permissions inside ROM MANAGER and form CWMR........NOTHING!!!! even got that dhcpcd fix thing that someone had posted,didn't work. and it's not just my home's wifi,i can't connect anywhere!tried rewriting wpa_supplicant file and the other stuff related to wifi(can't remember)with that wifi fix .zip fil manually, by flashing, using the files on other ROMs,NOTHINGGGGGGGG! WiFi only works with a clean reinstall of the ROM and WITHOUT SIM inserted. even tried with a SIM that had no PIN, same thing. i even downloaded AOKP,flashed, doesn't even boot.i don't wanna go around downloading every ics ROM i see so PLEASE give me a fix!!!

WIFI ERROR \ Turnning on \ Wifi Goes To Grey

Hello Everybody ... Am a new member to Xda site but i learned alot through reading your posts long time ago...
anyway here is my problem MY GALAXY NOTE GTN7000 Wifi Is not Working....
Details: I Had The phone since febraury 2012 and it was GB 2.3.6
i Updated to I.C.S 4.0.3 Official Rom and rooted it in july 2012
suddenly in august 2012 the problem started to appear ((( Am Writing Dates so To Avoid the Possibility of Hard Brick or anything because the phone was working great till then )))
THE PROBLEM
1-When I Try To Open Wifi It just Lag and stop responding The ICON GOES TO GREY INSTEAD OF GREEN and stays like that till Reboot and some times stays grey after Reboot
2- when opening wifi from settings tab it says "Turning On Wifi " and stays like that Forever
3- the only Way To restore the wifi icon to white is trying to activate WIFI - Direct
4- Rebooting Used to fix the problem but now NOT
5- Removing the battery Used to fix the problem But NOW NOT
Fixes I Tried
1- Restore Factory Setting & Wipe Cache & Wipe Everything
2- Changing the Rom from (I.C.S 4.0.3 )to (GB 2.3.6 ) to (Paranoid Android ) to (I.C.S 4.0.4)
Sometimes after each format or rom flash wifi worked for 2 hours or even 24 hours normally then problem appear
3- Tried removing Wpa Supplicant ( Helped Sometimes Then NOT )
4- Tried Wifix TO change country code even manually did it
5- Adjusted the Nfram_Semacove i dnt remember the name actually from CC To All ( Worked then later Stopped )
6- Used Wifi Rescue (Worked for a while then Stopped )
7- I Flashed Alot of kernels ((Heared that syiah Kernal Fix this problem but nothing out for NOTE YET )
HELP
I know that many will think that its a hardware ISSUE BUT IF Its hardware then why sometimes it work !!!!!
What i really Think is : Its a BUG Changed some files of the system which are not restored by flashing new ROM !!! for example when i Flashed Roms and Kernels i Found WPA Supplicant unchanged with my router Config !!!!
I SENT THE PHONE TO CUSTOMER SERVICE AND THEY SAID WILL CHECK AND REPLY within24 hrs but for sure its hardware and change Board which means 2800 EGP which is the price of new SGs2 soo am sure its a Bug or Software CAN ANY1 Help MEEEEEE

I am also facing the same problem for last one month and tried almost all the options tried by you but no relief. Wifi just works some time and other times it stays greyed. Can any one suggest any other solution as i also think it's software problem.

jesus christ, we are not BLIND!
anyway, i have same issues on sgs2

Same issue
@MOHPHR : I am facing the same issue as you.
I tried several ROMs from Original stock ICS to Paranoid to Crisleko's ROM.
Going into the airplane mode and then turning wifi on used to work, not anymore.
3G Data works just fine, not being able to use wifi is frustrating because when I leave it alone, it connects by itself randomly when I am at home for example.
I have done some extensive research and found an article that mentions wifi hardware problems resulting from ICS update on a galaxy S2. (Google: Samsung Galaxy S2 WiFi Issue BY Shaiful Borhan )
I did use the *#*#526#*#* and got the status: "NotSet Driver loaded [NG]".
Anyone can help please ?

Hi, I have been looking for days now for a forum that will be discussing this exact problem. I ve had this issue fora month or so now. I have restored to factory settings but it has not solved the problem. My galaxy note n7000 is not rooted nor does it have any special rom. I wouldnt even know how to install them. Where you able to find a fix? I am so tired of this problem, Im even contemplating the possibility of getting a note 2 and selling my n7000. I believe as well that it is most likely a software problem and im wondering if the soon to come jellly bean update could fix this issue.
Ps: after the wifi problem started, ive also noticed freezes and restars/ reboots.
Thanks for your help guys.:good:

@fedetipito I am still considering the hardware issue, although it seems a compatibility issue with the region/country as @fearkillerr mentioned in this post (http://forum.xda-developers.com/showthread.php?t=1436683)
I tried his solutions, none worked. The script one worked, but only once, then the problem kept repeating.
I upgraded to JB 4.2 then downgraded to stock GB 2.3 still the same issue. I am from the North Africa/Middle-East region, although when I was in Sweden in holidays and using a Swedish sim-card didn't have this issue. Any thoughts ? This problem is really really upsetting as we cannot use the WiFi properly. I am seriously considering simply abandoning my Galaxy Note N7000 and go for an iPhone 5, simply because I cannot even sell it (since no one would like a smartphone that doesn't have a proper wifi working).

I am having almost same problem with WiFi after I installed Custom ROM.
I tried only one method and it worked like a charm.
Go to WiFi connections and tell your phone to forget the network you are connected to, then re log. This problem did not happen after that 3 days now. Good Luck.

@Valium10 we initially cannot connect to any WiFi network, so we can't "forget" them. I don't think it is a "wifi network" problem.

" although when I was in Sweden in holidays and using a Swedish sim-card didn't have this issue"
And if you take SIM card out and power-on phone?Will wifi work?

Sometimes no, sometimes yes. It's kind of a malicious bug.

I am also facing the same problem and it seems it is hardware problem. May some dust or something else on the hardware or else we have dropped our phone some problem is there. When I gave to service center they asked that the motherboard needs to be replaced. But they refused to check it without that. I told that first try without replacing any parts and just check whats wrong in this if some repair can be done, but the service center people are so busy 50-60 peoples were waiting in line behind me to give there phones for service. They do not listen anything. They have tried by installing latest ROM and nothing else, that we can easily do it and for that also they have taken service charges.
Please someone tell me where exactly the wifi module is there, so we can open and check the problem ourself.

[Q] Problem LTE Galaxy S3 Wifi and Mobile Internet

Hello everyone,
As the title says I have a problem on my S3 (i9305).
First of all I want to know that it has been dropped or anything,
I put the official version 4.1.2 (the DBT for Germany was the latest then) instead of 4.0.4, rooted + busybox + modem network Vodafone Romania (XXBLL5) and it worked just fine until yesterday.
I arrived at work I checked my mail via wifi network, I disconnected I put on charger and after an hour I removed to make some mail and then give it to initialize wifi stupor show he wants to start and stop and did not want in any way to start a (looks like starts and stops).
Good now seeing that I got it and I somewhat empirically and did the following things:
-clear cache, wipe Dalvik, reset permisions - still did not work
-restore the Nandroid for wifi - did not work
I managed to got mad and threw factory reset - still not working height
-continuing with nervousness I flashed phone about 4 times with different versions 4.1.2 and version 4.3 but bootloader of 4.1.2-
Normally he did not want none and some gave the "camera failed" error.
All versions have been flashed after wipe cache, dalvik and factory reset so I say something to remain excluded from one another.
Now I'm on a Vodafone version 4.1.2 on sammobile after I haunted a bit on the internet I saw that its more people with this problem and someone had an alternative after you rename the file "wpa_suplicant.conf" in root / data / misc / wifi.
I did this and go but it is something temporary peak for once stop or restart your wifi is not working and another thing
mobile internet does not work without you come in APN and reset its there.
Sorry I did read both but I do not understand the phenomenon and to solve it because there can not be a hardware problem but rather a problem or write permission on the root folder.
And now comes the question: is there a solution to my problem or a way to see if some parts are protected to rewrite or corrupt?
Sorry for my english i use google translate.

[HELP] No IMEI and signal

Hello guys,
Short version:
My O4X suddenly lost signal and IMEI, look likes hardware problem. But when I reflash with V20A kdz, it works then after few restarts, It happens again.
Any help will be appreciated. Thanks in advance.
Detailed version:
- I was on CM11 nightly (20140923) for some time, it was smooth and no problem but then suddenly lost imei and signal.
- Tried to flash and wipe the latest nightly without luck
- decided to try the V20A kdz and it works again for few restarts (root and stuffs)
- Tried kdz without doing anything, just restart. After 3 restarts, lost IMEI again.
Thank you for your time and thank you in advance.
Also the friends here have similar problem but mine is still flashable... not sure for how long

I have your s problem and dont know what i will do. If you can. Please help me/

i have the same problem with my p880

I had the same problem...
In my case, as far as i can tell is hardware related.
The connection (imei and baseband) returns only if i use brute force, and start to press the phone very hard near the edges, near the the sim. .But they disappear if i turn off or reset the phone...

Is hard to take pictures because this is not a tutorial, i press different parts every time i lost my imei, until it works. What i do is pressing really hard (even bending a little the phone) everything above the battery, especially the sim card holder. Sometimes take 5, 6 , 7 attempts until the signal returns. When the phone turns on wait a little, because takes a few minutes until the signal returns.

I have kind of the same problem, but with slight differences: if I restart the phone, most times than not I get the signal back (at least for a few more hours) and using Zaiben's RC17 ROM it manages to get the signal back by itself after a while, no reboot needed. What I've found to be a "hack/solution" for this problem is to use the app Tasker to change network mode from 3G to 2G when the screen turns off. It appears than while in 2G this problem doesn't present itself...

@sergiohinniger apparently your brute-force method kinda works for me as well.
My phone started losing IMEI and baseband version after I replaced the audio jack and "small" PCB (the one with USB - now I'm back with original one). I then re-chcecked all connectors and coaxial cable, but the issue persists.
I think it works after few reboots with pressure on the back, so I believe that most likely it's caused by some bad cennectors. I have no idea though what to do with that Help, anyone?

It's true, with Zaiben or any stock roms the signal returns far more easily and sometimes resists the reboot. But now i have a new problem, the mac address, even when the signal returns, stay 00:00:00:00:00:00. I can only fix with a mac spoof app. This problem doesn't happen when i use custom roms, but the 3g signal is harder the return.

Some news, bad news
I have asked some repairers and here is their answer:
It's baseband file problem, if you have original Nandroid backup then it might help otherwise you can say bye bye to it
Click to expand...

basically, the baseband/IMEI file is damaged due to flashing rom, if you dont have origianl file, there is noway to save it
Sorry for bring back a dead post, I think it's a good infomation for people

Need Help "LOST IMEI and Baseband Unkonwn"
I was using Euporia 5.0.1 on LG 4x
I received update notification and I downloaded Update.zip ( which included to 5.1)
By mistake i flashed the zip directly from CWM ( without Formatting any partition )
after restarting there was no IMEI
Following things I have tried
1) Trying to flash Original V20C KDZ. via LG Flash Tool. ( I think it checks for IMEI , and that's why stuck in between)
2) Use LG Software Update tool. ( also can't progress with IMEI)
3) Flashed Original V20c Flashable zip from CWM (But it didn't restored my IMEI)
4) Contacted LG Service Center, and They say You need to change whole Motherboard. ( I was Shocked to know that )
:crying:
If anybody went to same problem. and resolved .
Please Guide me.

A repairer told me that some rom might contain RIL or baseband bugs that accidentally **** up our IMEI partition/files, so if you have NANDroid backup then try to restore it

OnePlus 3t Bluetooth not turning on

Hi guys I really need some help. It's been quite a few days now since my Bluetooth isn't turning on. I've tried clearing cache n data for Bluetooth apps and services in application manager but still no luck. This is what happens when I try to turn on Bluetooth... (Check screenshot)
The switch just fades and Bluetooth doesn't really turn on at all. And after a while the switch turns off by itself. Please help.
I also tried flashing another kernel (from stock) but still no luck. I'm on OOS 4.1.7 with Blu spark r174.

It had stopped working since I was on stock OOS (non rooted) and then I rooted and installed Blu spark but still no luck.

I have tried clearing app cache and data of Bluetooth share app, reset network settings even tried factory reset, still no luck. OOS 4.1.7.
Someone please help.

If it isn't working after factory reset, most probably it is a hardware problem..
Another issue that I've heard off is related to the encryption of the storage, but i don't think this is the case now

Another issue that I've heard off is related to the encryption of the storage, but i don't think this is the case now

But then the system acts weird about Bluetooth. When I try to turn it on (notice I do get an option to turn it on), the switch flips on the other side (switching ON) but fades n does nothing. And if I move out of settings and come back to Bluetooth section, it goes back to off. I kind of have a feeling it's a software problem n just needs some system modifications. But I really don't know, really need some expert opinions, please help guys.

Full wipe and try to downgrade to earlier OOS version..
( 4.1.5 ) or try another custom kernel ..EX or Dorimanx....

This happened to my dad on another phone and after a while the wifi died as well. It's a hardware issue.

I had the same issue 2 months ago. tried to switch back to stock and everything, it did not work. So I sent mine back to Oneplus, it was a hardware problem and the motherboard had to be changed. It sounds like you are unlucky as I was.

Just dirty flash your Rom and check if it works.

When folks say "factory reset" they most usually means just using the option "factory reset" in stock/custom recovery, or in phone Settings. All those do, is wipe user data. SO the problem will only be solved if some problem/incompatibility with user data was the culprit (does not actually "restore" any software/firmware).
I would suggest flashing the full 4.1.7 (or even early version) zip to restore to full stock, which I think is more what you meant.

This has happened to me before after updating magisk and not re-flashing a kernel. Wi-Fi and Bluetooth weren't toggleable (if that's a word) and the phones battery was draining pretty aggressively. I'd follow the advice from others and do a reset, or flash a custom kernel over what you have.
